OF CHECAGQ, ILLINGIS.

srssri-no sowoen SPECIEECATION forming part of Letters Patent No. %,921, dated December 20, 1887,

Application filed Jnno 7,1887. Serial No. 240;?)50. (No specimens.) Patented in Belgium Dcccmborill, 18B l ,ll f0- 15 83. and in England Jnnunry 18, 1857, No. T83.

To all whom it may concern.-

Be' it known that I, Gnonons AN'rncUNis, a citizen of Belgium, residing at Ghent, in the Kingdom of Belgium, have invented certain new and useful improvements in An Explosivc Iiowder; and I do hereby declare the following' to be full, clear, and exoctdcscription of the invention, such as will cnohle others skilled in the art to which it uppcrtnins to make and use tho some.

My invention, which was patented in Belgium on'thc 31st day of December, 1884-, No. 62,383, and in Great Britain on the 18th day of Jan unry,1887, No. 783, is a new snl'cty blast Lug-powder, which is intended to supersede ordinary gunpowder and dynamite for all industrial purposes, being at thcszrnie time not ob] y cheaper, quite as powerful, and perfectly harmlcss in handling, thcro being no danger whatever in making and using-it.

My powder is a combination of the fo1lowin ingredients reduced lo a finencss', sifted, nnu whcn perfectly dry tritnrntcd and mixed in revolving 'onrrcls: Mahogany sawdust, cight por cont; nitrate of potassium, lil'ty per cont; nitrnlc of soda, sixtccn per cont; charcoal, 1.5 pm sent, hlllllllilltbtii sulphur, cightcen pcr cont; ferro-cyzinidc ol' potnssium,thrcc per cent; picra-tc of ammonium, pcr cont; torn-l, one hundred per cent;

Tho relative proportions of the iibovc ingredients may of course be varied within it suits lilo range, occording to the cll'cct desired, and for damp climates the nitrate of soda might be dispensed with nlto cthcr.

The process of manufacturing the new safety blasting-powder is as follows: The ingredients are by 8. separate triturotion reduced to a vcry fine powder. Then they arc, each separately,

sifted, and at last put all together in a revolvo ing barrel and mixed until the incorporation is complete.

The powder thus manufactured is of a pologreenish color, very fine and dry, and ready for use. It can be used in the form of coinprcsscd cartridges, as isordinary gunpowder.

if compared to other explosives-such as gunpowder, dynamite, &c.'-it offers importout advantages: First, it is quite as powerful; second, it does not explode by concussion,

however violent, but only by ignition, and when lighted in an open space it burns briskly without exploding; third, when used for liring 2t mine, the stones, rocks, or minerals are smashed ordivided in huge pieces, (according 5 5 to the quantity of powder nscd,) but never projected to any considerable distance; fourth, it'is notobl y cheaper. The con'scquoncc is that my powder moy'bc manufactured, handled,

and stored without the least danger, (barring,

of course, the possibility of burning like any other inflammable substance, such as oil, tar, cotton, 8zo.,) and carried by boat or railway without any possible difficulty or objection.

Having thus described my invention, what 6 I desire to claim and scour-c by Letters Palcut is- The explosive compound composed of muhogan y sawdust, nitrate of soda, charcoal, subliinntcd. sulphur, form-cyanide of potassium, 7c
